Of course the degree of these color ranges I see on my monitor compared to you or another viewer on their own PC will differ greatly just because of different types of equipment we use to view the images on. I am wondering if you are shooting with lamps positioned about 10 and 2 o'clock or some other arrangement, and set about 45º to the coin. I see "hot spots" more around 11 and 5 o'clock.

You may need to move the light source further back (higher) from the coin or look for a cooler type of bulb. You can try shooting in day light also, but you will have to do a lot of work to create a space for diffusing the light and work near a window and during sunny days. Which ever situation you use for lighting, make sure you turn off ALL other light sources, which could even be light emitted from your TV or computer if it happens to be nearby.

If your camera body is black and creating dark reflections on your coin, you can cut a hole in the middle of a large sheet of white paper, poke the lens through it and effectively mask out the darkness your camera body, tripod and/or self is creating on the coin. Ideally you want to isolate the object (the coin), control and limit lighting source and intensity, and try to get your camera as far away from the subject as possible, while still getting a close up shot. I think getting your lighting under control will help, because you already understand your camera's functionality.
